Cable monkeys are used'lfor moving heavy or bulky articles vertically and horizontally. 1 One end of the cable is made fast'to a beam or other support, and theother end commonly ahangs free. p,

-.' The object of my invention isto'provide a cable monkey with driving gear,cable holdingdruins,slack adjusting means, and means forfstopping' and holding the load -on the fifcableyandi withothis and other objects "in Figure 4: is a similar view. on the line H,-

I Figure 5 is a vertical sectional view on the Iline 55, Figure 1.- 1 Figure 6 is a detail view. 1, v.' v 4 v I The Iirefe'rencefl numeral 6 designates the front plate of the housing, the rear plate being designated by'the number 7, the plates being secured to eachother by means of the b0lts8. 7 V Shafts 9, 10, 11, 12, are mounted in said housing. On shafts 11 and 12 are fixedly securedthecable winding drums 13, 14, while the slack controlling drums l5 and 16 are secured to the shafts 9 and 10, the drums 13 and 14 beingprovided with flanges 17. On the shafts 9 and I secure toothed gear wheels 18, 19, and on the shafts 11 and 12, I secure similar gear wheels 20, 21, the gear wheels and 18 intermeshing, while the gears 19 and 21 also intermesh.

' A shaft 22 is journalled in the housing and has keyed on it a pinion 23' which inter o meshes with gears 18 and 21,,said: shaft 22 being providedwith a crank24a.

. The shafts 9 and 10 are each provided with slackadjusters 24:, which are operated by the screws 25; The periphery of the slack drums 15 and 16 is provided with a friction element, i

such,f0r instance, as atireof rubber 26, the purpose of which is to hold the cable 27 in contact position againstthe drums 1-3 and 14:.

Pawls 28 and 29 are pivoted on the inner face of the plate 6 ofthe housing and are adapted for engagement with ratchets secured to the gears 20 and 21 of the cable drums 13' and'14, A manually operated rod30 movably mounted outside of the housing is provided at each end with an elongated slot'31 and 32 adapted to receive pins-33 which limit the throw of the rod. The pawl 28 is pivoted to theihousing, and is pivotally connected to, 0 the upper end portion of the rod as at 34:,

while; the pawl 29 ispivoted at its outer end 7 to the lowerend of the .rod 30, as at 35, the

pawl, being pivoted to the housing at 36 intermediate its ends so that with the pawls in engaging position shown in Figures 1 aud t anupward movement ofthe rod 30 will disengage the pawls 28 and 29 from the gears 13 and 14. The housing is provided with lifting cables 37 adapted, for engaging the load 38,

.said cables having hooks 39 adapted to engage the lower bolts 8 of the housing.

The upper end of the cable 27 is secured to asupp v 1 The load carrying cable 27 hangs loose below thecable monkey housing, but if desired the lower end of this cable may be attached to the housing. The cable is wound the desi'redfnumber of times-to the right on the, .drumYlB, and wound the desired number of 1 times tothe left on the drum 14, as shown in .Figurep3. The number of windings of the cable on its drums 13 and 14 is dependent on .theload to be carried.

flVith the load secured to the housing the crank 24 is revolved, which through the pinion 23 revolves the cable and slackdrums,

windingfthe cable around the drums 13land 14 whereby the housing is pulled and climbs upon the cable, thus lifting the weight 38.

' V Vhenit is desired to hold the load at a given Q point the pawls 28 and. 29 are in engagement with the ratchets of'the gears 20 and 2-1, but 1 :if it isdesired tolower the load, or let-it restI on a support, thebar30 is manually operated v to lift the'pawls out of engagement with the gears 20 and 21.' J I, 9

Thus it will be seen that-by myinvention I have provided drums and gears for moving -;;tl1'e load vertically or horizontally; means for holding the load in any desired position; means for'positive action in lifting, lowering,

moving, stopping and holding the load; and

means for holding the cable in contact with the pulling drums. a a 1 V In Figure 6 I show one end of the-shaft 22 journalledin a bracket A which. is 13secured'to the housing plate 6, the gear'whe'el 23 being on the shaft between the bracket .A .and the plate 6, sothat the shaft is journalled .in said bracket and Plate. i a What I claim is: g 1; "1.
